The reader must imagine himself at a spot distant about sixty leagues from Tubac. The sun, inclining towards the west, was already darting oblique rays; it was the hour when the wind, although still hot, no longer seems to come out of the mouth of a furnace. It was about four o’clock in the afternoon, and light white clouds tinted with rose colour, indicated that the sun had run two-thirds of his course; above, in the deep blue sky, an eagle hung motionless over the desert, the only visible inhabitant of the air. From the height where the king of birds balanced himself majestically, his eye could perceive on the immense plain, many human beings, some of whom were in groups, and others at so great a distance apart as to be visible to him alone, and not to each other.

Just beneath the soaring bird was a kind of irregular natural circle formed by a hedge of cacti, with their fleshy leaves and thorny points, with which were mingled the pale foliage of the bois de fer. At one end of this hedge was an elevated piece of ground two or three feet high, with a flat top, which overlooked it on all sides. All around this entrenchment, untouched by the hand of man, stretched arid plains or a succession of little hillocks which appeared like motionless waves in a sea of sand.

A troop of about sixty men on horseback had alighted in this place. The steaming horses showed that they had travelled fast. There was a confused noise of human voices, the neighing of horses, and the rattling of every kind of weapon—for it did not appear to be a regular cavalry corps. Lances with red pennons, muskets, carbines and double-barrelled guns were hanging from the saddle-bows.

Some of the men were cleaning their horses, while others were lying on the sand under the shelter of the cacti; a little further back were a number of mules advancing towards the halting-place, and behind them again, some twenty carts, heavily laden.

Visible to the eyes of the eagle, in the road along which these travellers must have passed, were corpses of men and animals strewn on the arid plain, marking the bloody track of this band of adventurers. Doubtless our readers have already recognised the Gold-seekers under the command of Don Estevan de Arechiza.

When the mules and the carts joined the horsemen, the mules were unharnessed and the horses unsaddled; the carts were unloaded and then linked together with iron chains, while the saddles of the animals were piled upon one another, and served with the cacti to fill up the spaces between the wheels and form a formidable barricade. The animals were tied to the carts, and the cooking utensils placed by the side, of the brushwood brought from a distance; a portable forge was established; and this colony, which seemed as though it had risen from the ground as by a miracle, was soon busily employed, while the anvil resounded with the blows which were fashioning horses’ shoes and repairing wheels.

A man richly dressed, but whose clothes were faded with sun and dust, alone remained on horseback in the middle of the camp, looking earnestly around him. This man was the chief of the troop. Three other men were occupied meanwhile in fixing the poles of a tent, and then placing on its summit a red banner on which was painted a scutcheon with six golden stars on an azure ground, with the motto, “I will watch.” The chief then alighted, and after having given an order to one of his men, who mounted and left the camp he entered the tent. All these preparations had occupied barely half-an-hour, so much were they simplified by habit.

To the right of the camp, but far distant, arose from the sand a mass of gum-trees and ironwoods, the only trees produced by these arid plains. Here a second troop had halted. They had neither carts nor baggage mules, but were about double the number of the other party. By the bronzed complexions of the riders, some almost naked, others covered with skins and with waving plumes of eagle’s feathers, and by the brilliant red and yellow with which they were painted, it was easy to recognise a party of Indians.

Ten of them—doubtless the chiefs—gravely seated round a fire which produced more smoke than flame, were passing from hand to hand the calumet or pipe of council. Their arms, consisting of leathern bucklers—surrounded by a thick fringe of feathers—axes, and knives, were laid by their side. At some little distance and out of hearing, five warriors held a number of horses, strangely accoutred with wooden saddles covered with skins. These horses belonged to the chiefs, and seemed difficult to restrain.

As one of the chiefs passed the calumet to the others, he pointed to a spot in the horizon. The eyes of a European would only have seen a slight grey cloud against the blue sky, but the Indian recognised a column of smoke—that rising from the camp of the whites.
